The pro ofiles ( V and V ) are preseented along X-axis and at Y= =0 z but by first shifting g the origin of the coorddinate system from cylinder geometr ric center to th he mean centeer of the vorteex core i.e. aloong a horizonttal line thr rough the vo ortex center. A simple alggorithm is useed to find thhe approxim mate average position of tthe vortex cennter.
